This is a calculator that finds out the optimal nutrition ratio and amount of food you should eat for your weight loss / maintenance goal. It includes a nifty prognosis chart at the bottom, once you’ve filled out everything.

All of the formulas and calculations are based on the most up to date research I could find. I have discussed most of the calculations at length in the /r/keto forum, where quite some scientific knowledgeable people hang out.

To the best of my knowledge, all the calculations are correct. Keep in mind that the data is based on the average person. Each individual is different, so the results might not be optimal for you.

I’ve got my cholesterol tested! Am I at risk?

In short, the only important factor is how many LDL particles (LDL-P) you have. Period. The parameters LDL cholesterol (LDL-C), Triglycerides, particle size matter only because they influence particle count (see below). When you have too many particles, you are at risk. If you do not know your LDL particle count, you simply do not know if you are at risk.

Imagine your bloodstream is a highway. You want to move a given number of passengers (called Cholesterol) from A to B, with as few accidents (crashes into your artery wall that build up plaque) as possible. How can you do this?

When you have only few passengers (low LDL-C), you can get away with using small vehicles (small LDL-particles) to carry them because this will not lead to lots of traffic. When you have lots of passengers to move (high LDL-C) and still use small vehicles, you will need lots of vehicles (high LDL-P) hence get lots of crashes (increased risk of CHD).

When you have few passengers (low LDL-C) but large vehicles that can carry lots of passengers, your highway is empty and you will have hardly any crash. You can also get away with lots of passengers to move (high LDL-C) when your vehicles are big enough that your LDL-P stays reasonable.

Now this is not the whole story. We got other passengers as well (Triglycerides) who want to be moved around as well. These guys take away precious seats that could otherwise be used to carry cholesterol. When you have lots of Triglycerides to carry around you will need a higher number of vehicles to carry the same amount of cholesterol. Again, more vehicles means higher risk, so high Triglycerides drive high LDL-P.
